Makers of the movie Oass (The Dew Drop), which is based on human trafficking, spent their days researching in the brothels of Delhi where they came across dingy holes where thousands of innocent girls are dumped to make money.

Abhinav Shiv Tewari, a debutante director, who has produced this movie inspired by a real story, said that the crew members including script writer and technicians went into the brothels of Delhi to know the ground reality, which was essential for the making of this movie.

"Some of them puked. There are small dingy holes where girls are dumped after being trafficked from different states," said Tewari, whose movie speaks about the heroic deed of a 11-year-old girl from Nepal who had managed to escape from the clutches of the trafficking mafia after spending five years in the living hell.

The movie was screened at the NFDC's Film Bazaar on the sidelines of International Film Festival of India (IFFI) 2012 currently underway in Goa.

The girl was later rehabilitated by a NGO.

Darjeeling-based girl Dibya Chhetri, who is a non-actor, has played the lead role in the film which also features Gangs of Wasseypur famed Yashpal Sharma and Jameel Khan, Subrata Dutta, who has acted in the upcoming Talaash, and Priyanka Bose of LSD.

"The movie brings to light the menace of child trafficking and the perils faced by many girls across globe," said Tewari.

The director said that the main motive of making this film was to take it to maximum people and tell them these inhuman stories about human trafficking.
